The gas-'engines inthe present instance are started by 'means ofcompressed air admitted to one of the cylinders oi' each unitthrough apipe c', having a valve c' withinreach of the operator when on theplatform H. .The pipes c lead from the air-cylinders K at one end of thebuilding to each gas-engine unit.

Each gas-engine has suitable regulating and governing devices tomake itof rate at. a constant speed whether the pump f l. ided or light.

In thepresent instance an electric igniter. is used for each cylinder ofthe engines; The igniters are controlled by switches It h It, on theswitchboard H', mounted on the platformH.' "l

In order to insure the v`proper working of the sparking mechanism, wehave so designed the apparatus that a primary or storage battcry can beused or the vcurrent canbe taken from a dynamo J,"drive`n from oneof theauxiliary gas-engines, or the eurren t may be taken from an outsidesource ol' supply, thus insuring an uninterrupted current.

Each pump unit A[has an independent suc# y tion-pipe IC extending7 intothe extension'l or sump a of the conduit A, andthis pipe E hasy afoot-valve E and screen e'.

N is the over-fiowspipe, forming a communication Ybetween the'pump andthe wastepipe G, which acts as a bypass when the pump is i'rst set inmotion, as it will be understood that the. pump does not immediatelypump water into the main B, but pumps it through the overflow-pipe intothe suc tionconduit or to waste. 'lhe overflow-pipe is provided with agate-valve n, which in the sscgess parlaient instanoes operated by anelectric mol-.cr n', the armature-shaft of the motor being geared to awheel on the' valvestem, as
